TSB81BA3EPFP

TRX, ONE PORT CABLE, 800MBPS, HTQFP-64.

The TSB81BA3EPFP is a Digital and Analogue Transceiver functions needed to implement a three-port node in a cable-based IEEE 1394 network. Each cable port incorporates two differential line transceivers. The transceiver includes circuitry to monitor the line conditions as needed for determining connection status, for initialization and arbitration and for packet reception and transmission. The TSB81BA3E is designed to interface with a link-layer controller (LLC), such as the TSB82AA2, TSB12LV21, TSB12LV26, TSB12LV32, TSB42AA4, TSB42AB4, TSB12LV01B or TSB12LV01C. It also may be connected cable port to cable port to an integrated 1394 Link + PHY layer such as the TSB43AB2. The TSB81BA3E can be powered by a single 3.3V supply when the VREG_PD terminal is tied to GND. VREG_PD enables the internal 3.3V to 1.95V regulator which provides the 1.95V to the core.
